Shapton 1000 vs Sigma 1200

[Steve Friedman]

For those of you who have tried both, how do they compare? I have the Sigma 1200 and it's great, but would love to try a no-soak stone in that grit range. I know that Shaptons are no longer the "it" stones, but just wonder if there is a big difference between the two.

By the way, I also have the Syderco ceramic set, but use them only for carving gouges and keeping them flat enough to match the flatness of my 6000 and 13000 Sigma's is not going to happen.

Just wondering.

They are both very hard. The shapton 1000 is a fair bit more coarse, though. I've never measured flatness, but if you used something that could actually shed grit from the shapton, the 1200 might be a bit harder and stay a little flatter. They are a different feel, though. The 1200 feels like you're sharpening with a non-glazed ceramic mug, and the shapton feels like you're honing on a block of dried epoxy.

...sharpening with a non-glazed ceramic mug...honing on a block of dried epoxy.

hmmm...I've never tried either. Maybe they would work. They certainly would be cheaper than the stones.

Thanks David,

I have Atoma diamond plates in 140 and 400 grit, so I'm not concerned about keeping the Shapton flat. I do like the feel of the Sigma 1200 (actually feels like something is happening), but just wondered if I'm going to be disappointed using the Shapton instead as a spray-and-go stone. Not trying to be smarmy, but I assume you're suggesting that a non-glazed ceramic mug (the Sigma) feels coarser than a dried block of epoxy (the Shapton), right? Or do I have it backwards?

Thanks again,

Steve

It's just a different feel. The hard bester (the 1200) and the sigma 1200 both have sort of a feel that they're filing the steel when you're using them. They pro shapton and the SP both very good stones (the glasstone 1000 is too soft in my opinion, especially with as little as you get in terms of abrasive). I doubt there's anything about either of them that you'd be missing or disappointed with. I haven't used the SP 1200 too much lately after getting ezelaps, so I'm a little foggy in terms of whether or not it benefits from the surface being dressed like the shapton does, but the shapton definitely does benefit from a quick 5 or 10 second refresh lap once in a while (which will end up keeping it flat, anyway).

If you ever get your fingers on a bester 1200, it has a feel of a coarse sigma 1200, and it's not quite as hard (obviously no reason to get it if you have either of the other two, it's just another one of the good stones - those three are my favorites of the stones available). They both have that hard coral feeling to them, the shapton has more of a greasy plastic feel to it (but not cheap or offputting in anyway), maybe because there's nowhere for the water to go in it. I think they are all desirable stones to use. They tell you what they're doing by feel and they're all relatively fast and uniform.

So I am in the market for a new 1000 grit stone. I have been using the Shapton 1000 for a long time and it is finally getting very low and has developed cracks. If you were to buy a new 1000 would you go with a Sigma 1000 instead of the Shapton Pro or something else? I have liked the Shapton Pro and really have no complaints, it has been a very good stone through out the years. But human nature (at least this human) always wants to know if something different is better or more appealing. Luckily this day in age we have the internet and can ask people with experience instead of being disapointed with something.

[David Weaver]

shapton pro 1000, SP 1200 or bester 1200

I can't see anyone having a real dislike for any of them. The bester and the shapton pro are a bit more coarse. The SP 1200 might be a bit harder, but it cuts a little finer.

Take your pick, though. If you've gone through a shapton pro 1k and really liked it, there's really nothing mounds better on the market.

Yeh same. Though I haven't used the Shapton Pro 1k. The sigma 1.2 is the bees knees, the bester 1.2k is also great...I've said it before and I'll say it again I'm also a big fan of my Chosera 800 (I think its a better stone than the Cho 1k) and the only stone I've used that I like as much and perhaps more than my 800 is the sigma 1.2k. That said, there is no good reason to spend an extra $30 or whatever on a Chosera (unless you specifically want a magnesia stone) when the 3 Dave listed are so excellent.

What's different about a magnesia stone? Can I go from the Chosera 800 to the Sigma 6000 without something in between or is the 800 too rough? I assume it's splash & go, right? Do I need a nagura stone for it?

Thanks.

Lets start with the easy questions. Yes you can go from a a Chosera 800 to Sigma 6k just fine. I've never had ANY issue with this. FWIW the Chosera 800 (according to one site whose information I can't verify but have no reason to believe is incorrect) has actually a slightly smaller micron grit than the Shapton 1k (14 vs 14.7 micron).

No you do not need a nagura although all the Chosera's come with a 600 grit nagura for "cleaning" I believe.

What's different about Magnesia stones (specifically the Naniwa Magnesia stones)...well at the end of the day nothing all that major but...

They tend to be very fast cutting for their grit range. They manage to be fairly hard but still have a nice feel. If you soak them for 10 or so minutes they work as nicely as any stone I've used...if you use them with just a spalsh they work anywhere from okish to quite well depending on the stone.

The downside, if you don't soak them they may or may not be not that nice to use (again depending on the specific stone). They fall into the soak but don't soak too long category and defintily don't permasoak. When they aren't working at they're best (which usually means they needed ot be soaked or soaked longer) they can misbehave...something about them (presumably their speed) tends to make them load in certain areas and they can get sticky when that happens.

They are sorta bimodal stones and there are trade off for their strengths. When they are good they are oh so VERY VERY good, but depending on the stone and how you treat it/soak it they can be finicky. The reason I like the 800 so much is for whatever reason it seems to have all the advantages but none of the disadvantages. I have no idea why, but it never clogs, where as if you work the 1k Chosera too hard and don't soak it enough it can clog (at least thats how Archies was).

Anyway I don't soak mine, but I ALWAYs let standing water sit on them for a while. The first thing I do when I get into the shop is wet them. They just work noticeably better that way.

I don't want to over emphasize their flaws. They are excellent stones, very fast, and again, dreamy to use IF you soak them and depending on the specific stone can be very nice to use even if you don't. I love mine. The thing is if you already have the sigma 1.2k it has those strengths and none of the flaws, in that it is nice and hard, still nice to use, and cuts VERY fast for its grit range. I believe (and stu correct me if I'm wrong) that the 1.2k really NEEDS to be soaked, as opposed to just working better with a soak like the Chos, but unlike the Cho's you can leave it in water permanently so I'd say its actually more convenient.

Anyway, I this is just my limited experience. Some of these stone I own or have owned, some of them I've only used in my friends shops. But based on that experience I would rank the Sig 1.2k and Cho800 as hands down my favorite "medium" grit stones and would give the edge to the Sigma 1.2k because it can be permasoaked. I'd give 3 way ties to the Bester 1.2k, Sigma 1k, and Cho1k (all of which are different with different strengths and weaknesses). Again, I can't rank the shapton 1k because the only Shapton I've ever used is the 5k. Long story short. If you own any of the stone Dave or I mentioned you pretty much have the best that's out there and there isn't any major universal gain from choosing one over the other.

I don't claim to be an expert at any of this. I just happen to have tried fair number of stones because of who I associate with. If anything I've said seems incorrect please defer to Stu, or Dave, or Joel, or whoever else has used these things more than me.

Another stone you might consider is the Sigma power ceramic stone, 3F carbon #700...

"This stone .... would be difficult to describe if it weren't for the existence of the 'Select II' series stones, which it very closely simulates in both the way it behaves and the way it abrades steel.

In short, this stone positively eats steel, it's always hungry and doesn't care what you feed it. From easy to sharpen white steel/iron laminated blades to the toughest High Speed Steels, this stone cuts fast without any fuss."

I had a Shapton 2000 Pro, which is reputed to be pretty close to the 1,000. So I bought the 700 and 3,000 Sigma Select II. The 700 appears to be several times thicker than Shapton stones and at least twice that of a regular Sigma Power or Sigma Select II stone.

[Steve Friedman]

Thanks Chris.

Great explanation. My only reason to try something else in that range is to find something that doesn't need soaking. I have used my Sigma 1200 without soaking, but it is clearly happier after a short soak. Regardless of the time of soak, the fact that it needs to be soaked at all is the issue. I recall reading that the Shapton 1K is happier with a short soak as well, but know that many people really just use it with a spray bottle. Your description of the Chosera makes it sound appealing, but it doesn't sound like a true no-soak stone. Decisions!

Thanks again,

Steve

Mike,

I have thought of the Sigma 700 several times, but if there is significant work to do, I start with a Cerax 320, then Sigma 400. By the time I'm done with those two, I'm just removing scratches or creating a microbevel and the 1200 is aggressive enough for that. Since I sharpened every blade I own after getting my Sigma stones, most of the work is on the 6000 and 13000. I only drop down if there's a chip to be repaired.

Thanks,

Steve

Chris G's Chosera 800 is genuinely superior to the Cho 1000. It's an amazing stone, and it's not nearly as messy (but neither are the 400, 600, or 3000). But, my Cho 1000 can produce more easily a sharper edge faster than every other 1k or 1.2k that I tried. At this, it beats the 800; but that's it. After using the Cho 800 & 1000 as well as the Sigma 1000 & 1200 and the Bester 1200, the Sigma 1200 and the Cho 800 stand out as the best. The Sigma 1200 has tons more feel and personality (IMO) than the Bester, both which cut faster than the Sigma 1000. Again, I get sharper here with the Cho 1000, but for prepping and handing off to the next stone, the Cho 800 (Chris') is decidedly faster and leaves a fairly sharp edge. The Sigma 1200 nearly matches the 800 in prep speed and excels it in edge quality. I'm still a fan of the Sigma 1000 because you cannot keep it from working--and it gives excellent feedback. The Bester 1200, though a lesser quality stone in terms of feedback, speed, edge refinement, still produces a heck of a good edge.

These are all great stones!!!!! It's been fun learning how to coax the best from them. The Sigma 1200 and the Chosera 800 are the easiest with which to do so.

Sigma 1200 vs Shapton 1000?

As David notes, the Sigma feels slightly coarser - very slightly in my estimate. Just a little more feedback. Nevertheless, the Shapton performs identically, or nearly identically. I doubt that you would notice the difference. I have the Sigma 1200/6000/13000 and, taken together when used on tough steel, they are prefered to the Shaptons. Nevertheless, the Shaptons are excellent stones and have certain advantages, namely that they work better with less water. The 1000 is the star of their show as far as I am concerned. For the current project I switched to the Shapton 1000/5000/12000 combination, and am not feeling a drop in performance.

EDIT: I have just returned from 4 hours in the shop dovetailing sides for a chest, which involved preparing the chisels to do so. I put the Shapton 1000 and Sigma 1200 alongside one another. There was a difference in feel, but it was the other way around - the Shapton has a coarser, more direct feel. The Sigma feels smoother and glassy by comparison. Both were flattened on a Shapton diamond flattening stone. Both work comparably, with an edge to the Sigma on the harder PM-V11 steel, but the same on O1.
